Description

Technical Field

[0001] The utility model relates to the technical field of laser cleaning machines, in particular to a positioning device for laser cleaning machines. Background Art

[0002] Laser cleaning machines use laser cleaning technology, which is a cleaning solution that uses high-frequency short-pulse lasers as the working medium. High-energy beams of a specific wavelength are absorbed by the rust layer, paint layer, and contamination layer, forming a rapidly expanding plasma and generating shock waves, which break the contaminants into fragments and remove them. The substrate will not absorb energy, damage the surface of the object being cleaned, or reduce its surface finish.

[0003] When using a laser cleaning machine, the workpiece needs to be fixed on the surface of the processing table, and then the surface of the workpiece is cleaned by holding the laser head or clamping the laser head with a clamping mechanism. However, after cleaning one surface of the workpiece, the angle of the workpiece needs to be adjusted before cleaning the other surface, resulting in the cleaning process being not continuous and flexible. Therefore, the utility model proposes a positioning device for a laser cleaning machine. Utility Model Content

[0023] When the vertical rod 4 moves, the two extrusion plates 53 can be driven to move closer to or farther from each other, so that the extrusion plates 53 are used to squeeze and fix the workpiece.

[0024] A locking bolt 42 passes through the top of the through hole 41 and is threadedly connected thereto.
